Stereoscopic acuity - Wikipedia
Stereoacuity is defined as the minimum angle detectable, calculated as the difference between the angles subtended by both positions, A and B. Stereoacuity is possible due to binocular disparity, i.e., the difference in their binocular parallax.
Stereopsis and Tests for Stereopsis - EyeWiki
The brain is then able to detect the binocular disparity, stimulating disparity-selective neurons to fire an increased number of action potentials and encode the relationship between the two images. As a result, depth can be perceived in a phenomenon termed “stereopsis [1] [2].”.
Stereoacuity Definition & Meaning | Merriam-Webster Medical
The meaning of STEREOACUITY is the ability to detect differences in distance using stereoscopic cues that is measured by the smallest difference in the images presented to the two eyes that can be detected reliably.
Stereo vision and strabismus | Eye - Nature
2014年12月5日 · Binocular stereopsis, or stereo vision, is the ability to derive information about how far away objects are, based solely on the relative positions of the object in the two eyes. It depends on...
Normative Values for Near and Distance Clinical Tests of Stereoacuity
Individual stereotests cannot be used interchangeably-knowing the upper limit of normality for each test is important. This report details normative stereoacuity values for 5 near/distance stereotests drawn from a large sample of participants aged 16-40 years, across 3 studies.
Effects of Target Size and Test Distance on Stereoacuity
2016年8月21日 · Stereoacuity should be estimated by both parallax and other elements, including test distance and target size. 1. Introduction. Stereoacuity tests can be carried out easily and quickly to detect strabismus and amblyopia and to judge the degree of binocular vision after refractive correction [1 – 5].
Clinical Measurement of Stereoacuity | SpringerLink
2024年7月4日 · In this chapter, we discuss many of the clinical tests of stereopsis and stereoacuity currently in use. The methodology of the tests, the normative data from these tests, and the clinical significance of these tests will be described.
Defining Real Change in Measures of Stereoacuity
2008年5月21日 · To define real change in stereoacuity, we compared performance on 4 tests of stereoacuity (preschool Randot, near Frisby, distance Randot, and the Frisby–Davis distance [FD2] stereoacuity tests) in patients with stable strabismus across 2 …
The difference in stereoacuity testing: contour-based and random …
2019年3月14日 · Two types of test graphs commonly used in clinical stereopsis testing are contour-based [e.g., Titmus circle test (2)] and random dot-based [e.g., TNO test (3), Lang stereo test (4)]. The former stereopsis tests are called “local stereopsis”, while the latter tests are called “global stereopsis”.
Treatment of Bilateral Refractive Amblyopia in Children 3 to …
Stereoacuity. Of the 94 children who had stereoacuity tested at both baseline and the one-year examination, stereoacuity had improved a mean of 1.9 levels (95% CI = 1.4 to 2.3), with 56 children (60%) improving two levels or more (Table 4). Improvement in stereoacuity was associated with improvement in binocular visual acuity (P=0.02).
